2D Semantic/Instance Segmentation

Semantic Segmentation

Overview: Semantic segmentation is the task of classifying each and every pixel in an image into a class or category. 1. Select an instance or semantic segmentation by clicking “Label” at the top panel

2. Draw an object with a polygon using the left mouse click. 3. When you are labeling objects in the semantic if the objects are touching each other than their drawn polygons are merged with each other with a single id. 4. In the below image, you can see the merged polygons with a single id

Instance Segmentation:

Overview: Identify each object instance of each pixel for every known object within an image.

1. Select an instance or semantic segmentation by clicking “Label” at the top panel.

2. Draw an object with a polygon using the left mouse click. 3. When you are labeling objects in the Instance segmentation, each object can be labelled distinctly with a unique ID. 4. In the image below, you can see the object’s polygons with different IDs like Car1, Car2 and Car3.
